<small>There is a new edition of the book and this is an old link.</small>

Vectors store more than one value in a single data structure that puts all the values next to each other in memory. Vectors can only store values of the same type.

let v: Vec<i32> = Vec::new();
let numbers = vec![1, 2, 3];

Here are the relevant sections in the new and old books:

• in the current edition: Ch 8.01 — Vectors
• <small>In the first edition: Ch 3.7 — Vectors</small>
